Well this is my very first technical post and I am hoping someone can lead me in the right directioin. So I am trying to fix a squeal/squeak coming from my serpentine belt/pulleys. It seems intermittent doing every so often and at start up/shut off. I replaced a new Napa (Gates) serpentine belt, Napa Tensioner pulley, and Napa Idler pulley. I then noticed when I was changing the idler pulley, that the sleeve on the new pulley didn't turn easily and make contact with the black threaded sleeve that fits over the idler pulley bolt, but thought maybe was due to tighter/newly packed bearings with no wear unlike the orginal pulley. Does this black sleeve need to be replaced too? After I replaced all of this and put new belt back on, I still couldn't eliminate the squeal. I've heard something about a camshaft postion sensor, but don't know anything about them. I have added links to videos which will take about 30 sec to 2 min to load for each video, if the screen is just black, be patient, it will load soon enough. Any suggestion or comments are always appreciated.
